SIGN.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed February 24, 1920. Serial No. 360,796.

To all whom it may concern Be it known that 1, JOHN C. MONAHAN, acitizen of the United States, residing at Duluth, in the county of St.Louis and State of Minnesota, have invented certain new and usefulImprovements in Signs, of which the following is a specification,reference being had therein to the accompanying drawing.

his invention relates to signs and has special reference to a barberssign.

The principal object is to produce a particularly attractive andinteresting sign of this character.

Other objects and advantages of the peculiar construction will appear asthe description proceeds.

In the accompanying drawings forming part of this application and inwhich like reference characters indicate like parts:

Figure 1 is a front elevation of one embodiment of my improved sign.

Fig. 2 is an enlarged central vertical sectional view.

Fig. 3 is an enlarged fragmental section showing the ends of the rollsand the operat ing device in elevation.

Fig. 4L is a front elevation of a modified form of sign involving theprincipal elements of the invention, and

Fig. 5 is a perspective view of a modified form of the moving elementswithin the sign.

1 represents a suitable housing preferably rectangular in shape, in thefront of which is installed a glass 2.

lVithin the housing and disposed horizontally, one adjacent the upperportion thereof, and one adjacent the lower portion of the housing aretwo rollers 3 and 4-, mounted upon suitable shafts 5 and 6 respectively,which are journaled within the side walls of the housing.

In the preferred construction here illustrated the central horizontalportion of the glass 2 is made opaque, by painting or otherwisecoloring, preferably the inner surface thereof, and upon whichtransparent letteringor other form of indicia, as indicated at 7 isplaced. The opaque strip through the center of the glass is of avertical width to leave just suflicient transparent portions of theglass through which the major portion of the rolls 3 and 4: are visible.

Within the housing and approximately centrally thereof is installed anelectric light, as indicated at 8, which when desired may be turned onfor illumination of the entire sign as is obvious.

Upon the exterior of the rollers 3 and a are bi-colored markingsdelineated spirally in opposite directions in respect to the rollers sothat when they are rotated in the same direction which is the result bythe mechanism hereinafter described, the optical illusion of horizontalmotion will occur in opposite directions thereupon.

its operating means for the rollers I have shown fixed to each rollershaft, and close to the ends of the former, a suitable sheave 9 and justbelow the shaft 5 is installed in the adjacent edge wall of the housinga counter shaft 10 fixedly carrying a sheave 11 and a spool 12, thelatter being in alineinent with the sheaves 99 and the former inalinement with the driving pulley 13 on the electric motor 14; supportedupon a suitable bracket 15 attached to the wall of the housing and whichnrotor may receive electric energy from any source desired.

The driving belt from the motor to the sheave 11 is illustrated at 16and the belt 17 is wound once around the spool l and around the sheaves99 which results in the two latter being rotated in the same direction.

lVhile I have shown this arrangement as a preferred embodiment it isapparent that the spiral colorings of the rollers may be alike and thebelt 17 crossed to produce opposite motions of the rollers and variousother modifications from the installation here shown may be resorted towithout leparting from the spirit of the invention.

In Figs. 4 and 5 I have shown the rollers 3 and 4 as carrying acontinuous or endless curtain indicated at 18, such curtain havinginclined markings adjacent its edges as at 19 and centrally disposedspots or space." of different colors as indicated at 20. Upon tl e glassfront of the sign the opaque space indicated at 21 is disposedvertically of the face of the sign and carrying transparent indicia, thecolor of which will change as the difierent patches of color on thecanvas pass therebehind.

In this modification the light may be installed from the side edges ofthe housing intermediate of the rollers and shine through the belt orcanvas 18, which would he of more or less transparent material suitablefor such use.

7 Having thus described my invention; what I claim as new and desire tosecure by Letters Patent is:

1. The combination with a reetangularly shaped housing having a glasscovered front, of two horizontally disposed spaced rollers havingstripes thereupon spirally disposed in different directions, and meansfor rotating the rollers in a like direction whereby the stripes areseen to move horizontally in diiierent directions.

2. In a sign of the character described, the combination with a suitablehousing having horizontally disposed spaced rotatable rollers therein,0*? a glass front for the housing having a transparent space in front ofeach roller and exposing same to view and an opaque space intermediateof the transparent spaces carrying indieia thereupon.

3. In a sign of the character described, the combination'with a suitablehousing carrying horizontally disposed, spaced rollerstherein and meansfor rotating same, of varicolored covering for the rollers a glass frontfor the housing having a central opaque portion and two spacedtransparent portions substantially as and for the purpose deeribed.

In testimony whereoi l hereunto aflix my signature in the presence oftwo witnesses. JOHN C. MONAHAN.
